I have designed an inverter using nmos4 and pmos4(NCSU_Analog_Parts) and edited the width and length with varriable Wid and Len. After changing the Drain Diffusion Area value becomes Wid*2.5*iPar("MinL") as it should be.

However every time i try Netlist and Run, i get the following errors

"input.scs" 17 : Function 'iPar' is undefined or is used recursively
"input.scs" 17 : Function 'iPar' is undefined or is used recursively
"input.scs" 18 : Function 'iPar' is undefined or is used recursivelyl
"input.scs" 18 : Function 'iPar' is undefined or is used recursively
"input.scs" 20 : Function 'iPar' is undefined or is used recursively
"input.scs" 20 : Function 'iPar' is undefined or is used recursively
"input.scs" 20 : Function 'iPar' is undefined or is used recursively
"input.scs" 21 : Function 'iPar' is undefined or is used recursively

I tried to edit CDF parameter for nmos4 and pmos4 by trying to edit paramenter MinL(assuming this is source of error) as parseasCEL = yes and parseasNumber = yes. But it did not improve a bit. Please tell me what to do.

Note : i was following this tutorial and did exactly what is said but same errors.

No, i meant iPar().
I could solve the problem by setting up the following environment varriable.

setenv CDS_Netlisting_Mode Analog
